Reinforcement will be done with an injectable vaccine after the transition period
The Ministry of Health will gradually replace the oral polio vaccine with the inactivated version of the vaccine starting in 2024. The recommendation was discussed and approved by the Technical Advisory Committee on Immunization, which considered new scientific evidence for protection from the disease.
This update does not represent the immediate end of the immunizer in the version popularly known as a droplet, but rather a technological advance for greater effectiveness of the vaccination program to be carried out after a transition period, the ministry said.
inactivated vaccine
The recommendation from the technical chamber was that Brazil adopt only the inactivated polio vaccine in the booster at 15 months of age, which is currently done with the oral form of the vaccine. The injectable form is applied at two, four and six months of life, according to the National Vaccination Calendar. Therefore, after a transition period starting in the first half of 2024, Brazilian children who complete their first three doses of the vaccine will only get one booster of the injectable vaccine at 15 months.
The booster dose currently applied at four years will no longer be required, as the four-dose vaccination schedule will ensure protection against polio. The update took into consideration epidemiological criteria, vaccine evidence and international recommendations on the matter.
Company movements
The new recommendation was presented by the Minister of Health, Nisia Trindadewith the Brazilian Society of Pediatrics (SBP), last Friday (07).
“The resumption of high vaccination coverage is a priority for the federal government. This is a movement, not an isolated campaign, precisely because of the idea of continuity and constant monitoring of results. This work is not limited to the Ministry of Health, reason whereby we are going where the movements of society are“explained the minister.
No cases of polio have been reported in Brazil since 1989, but immunization coverage against the disease has declined successively in recent years. Across Brazil, coverage was 77.19% last year, far from the 95% target for this vaccine. Therefore, the mobilization to resume the high vaccination coverage in the country, which was once an international reference, is fundamental.
Strategy
The idea is that the municipality organizes and plans taking into account the local situation. In this sense, the immunization strategy will be adapted according to the population, the health facility and the socio-economic and geographical reality.
Among the strategies that can be adopted through micro-planning by the municipalities are vaccination in schools, active search for unvaccinated subjects, vaccination in every contact with a health service, extramural vaccination, control of the vaccination record and the intensification of vaccination in indigenous areas.
Based on this strategy, multivaccination has been anticipated in border states, such as Acre and Amazonas. The next state to receive this action will be Amapá, starting July 15, with a vaccination D-Day.
